8021: Recording each patent assignment, agreement or other paper, per property – if submitted electronically – fee decrease from $40 to $0.(If not submitted electronically, the fee amount remains $40.)

According to this Federal Register Notice, these fee reductions were made to help rebalance the fee structure and offset the increases in filing, search and examination fees that were implemented in 2013. Interestingly, the USPTO acknowledged that they intentionally delayed the implementation of these fee reductions in order “to allow the Office to recover sufficient revenue to pay for the projected cost of patent operations” in 2013.
